Title

pretalx: Stored cross-site scripting in organiser search typeahead

Summary

pretalx is a conference planning tool. Prior to 2026.1.0, The organiser search in the pretalx backend rendered submission titles, speaker display names, and user names/emails into the result dropdown using innerHTML string interpolation. Any user who controls one of those fields (which includes any registered user whose display name is looked up by an administrator) could include HTML or JavaScript that would execute in an organiser's browser when the organiser's search query matched the malicious record. This vulnerability is fixed in 2026.1.0.

Severity ?

Vulnerability from github – Published: 2026-04-18 01:11 – Updated: 2026-04-18 01:11

Summary

pretalx vulnerable to stored cross-site scripting in organizer search typeahead

Details

The organiser search in the pretalx backend rendered submission titles, speaker display names, and user names/emails into the result dropdown using innerHTML string interpolation. Any user who controls one of those fields (which includes any registered user whose display name is looked up by an administrator) could include HTML or JavaScript that would execute in an organiser's browser when the organiser's search query matched the malicious record.

Triggering the vulnerability required:

An attacker-controlled field reachable by the search, which included any speaker's or submitter's display name in an event context (submitted a proposal) or any user at all for superusers.
An organiser user with more than just review permissions or administrator user performing a typeahead search whose query matched the malicious record. An attacker can make matches likely by placing common substrings in the payload-bearing field.

Once triggered, the injected script executed in the context of the pretalx organiser interface and could read the page's CSRF token, submit authenticated requests on the victim's behalf (including requests modifying data due to access to the CSRF token), or exfiltrate data visible to the victim.

Patches

Fixed in pretalx v2026.1.0.

Workarounds

There is no configuration-level workaround. Operators who cannot upgrade immediately can avoid using the organiser search bar, or apply the patch to src/pretalx/static/orga/js/base.js manually and re-collect static files.
